Steve's Notes
=====
NGC 4728
18" (4/10/04): faint, small, round, 20" diameter, no noticeable concentration. Forms the north vertex of a thin triangle with a mag 11 star 3.3' S and a mag 13 star 3.8' SSW. Another 3.6' S of the mag 11 star is NGC 4721 (6.8' SSW). Located 18' WSW of mag 4.9 31 Comae Berenices and a similar distance ESE of mag 5.8 30 Comae!
17.5" (3/20/93): faint, small, round, even surface brightness. A mag 11 star is 3.3' SSW. This outlying member of AGC 1656 forms a trio with NGC 4728A = UGC 7992 2' ESE and NGC 4728B 3.5' NNE. NGC 4745 lies 13' E. Located 18' SE of 30 Comae Berenices (V = 5.8) and 17' SW of 31 Comae (V = 4.9). The CGCG magnitude =15.6z is too faint.
